RE: [Repeater-Builder] Motorola TLD-1100 Wanted,please help if you can.
Hi,after I just e-mailed you I got thinking,my friend wants to hook up the old bag phone to the head.You guys in this club are much more knowledgable on the old stuff than he is so I figured I would ask if this is the best way to do it. What would you advise ? I would put in a whole unit if it's easier but I don't know how to hook it up to the modern cell networks.The bag idea is just what we were thinking was the easiest,any advice would be great,Greg.

Chuck- My Ebay account was hacked a few years back. The way you get it back is to contact support there, and they will call you at the phone number on record to verify. But you initiate it all, not them. And I don't remember a SSN ever being used with Ebay. Are you actually not able to get into your account? Have you tried? And I mean by entering ebay.com to browser, not following a link in a phishing e-mail. GeorgeC W2DB

[Repeater-Builder] Guideline for scanning manuals?
What are the guidelines for scanning manuals for the RB site? I want to scan upload the manuals for the MSR 2000, but they are HUGE... Tried doing the VHF manual today at 200 dpi, and even choosing Acrobat's reduced file size option, it came out to 101 MB!!! (the UHF and Audio/Control manuals are coming any day) I presume they should be scanned in BW, not greyscale or color (unless needed for images/PC board layouts...), but at what resolution? And Kevin or Mike, can you send me the ftp instructions again? I seem to have lost them.. George, KA3HSW / WQGJ413

RE: [Repeater-Builder] Guideline for scanning manuals?
George, I do a lot of manual scanning, and I have evolved a standard of sorts that I personally follow, and recommend to others. This is a personal preference, and should not be considered a requirement for any submission to be published on the Repeater-Builder site. Herewith are my personal preferences: 1. Always scan directly into PDF as a document, never into any image format such as JPEG, JIF, or TIFF. 2. Always scan at 300 DPI resolution, to maximize laser printing clarity without making the files too large. 3. Always scan schematics and text as 1-bit (line) drawings, with the white and black points set for optimum contrast and density. 4. Scan photographs and color separations as 8-bit (gray scale) drawings, if necessary to preserve detail. If not, scan as a line drawing. 5. Never make segmented scans of long pages. Take those pages to a graphics shop for full-page scans into PDF. 6. Always scan pages as they are bound, so that all scans are 11 inches high regardless of orientation or length. (PDFs are automatically rotated for printing) 7. Always add page numbers, using the Adobe Text Tool, when they are missing. 8. Always add a note to indicate if a following page is blank. 9. Don't scan irrelevant pages, such as how to order spare parts from depots that haven't existed for years. 10. Never scan and submit for publication any manual that is still in print, unless you want to be sued for copyright infringement. I prefer to use Adobe Acrobat 4.0 Professional for most scanning, and I then perform optimization in Adobe Acrobat 7.0 Professional. The result is a document that is not only versatile, but is much smaller than any image format. Long pages can be printed on a document (roll) printer at most commercial graphics shops, along with many Kinko's shops. The real beauty of PDF is that a portion of any long page can be selected using the Adobe Reader Snapshot tool, and then printed on standard 8.5 by 11 inch paper. For example, you might want to print just the final stage in a power amplifier schematic diagram that was originally almost three feet long. Just use the snapshot tool to select that portion, and now you have exactly what you want. You can also save that selection as a separate PDF to send to someone in an e-mail. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of George Henry Sent: Thursday, October 23, 2008 2:33 PM To: repeater-builder@yahoogroups.com Subject: [Repeater-Builder] Guideline for scanning manuals?

[Repeater-Builder] DB antenna question
I'm running out of antenna mounting positions at my site. Has anyone tried any of the following ideas and if so what were the results ? The intent here is to run 2 rptrs. using a common mast to support 2 antennas. 1. Mounting the dipoles and harness from a UHF DB420 on the same mast as a VHF DB224, or vice versa. (UHF and VHF antennas on the same mast) 2. Mounting the dipoles and harness from a DB420 on the same mast of an existing DB420.(2-DB420 UHF antennas on the same mast) 3. Taking an existing DB420 antenna and feeding the upper and lower halves with separate feedlines to make 2-6 Db antennas on the same mast. The lower harness section would be replaced with with the upper harness section from a junk antenna. In 1. and 2. the dipoles of each antenna would be at right angles to the existing antenna. In 3. the overall gain of the single antenna would be reduced to about 6 Db for the upper and lower halves. Additionally extra filter cavities would probably be required to keep the 2 rptrs. using the antennas from interfering with each other. If any of the above ideas are practical this would allow me to recoup some additonal mounting positions or at the least reduce the clutter of antennas I have now. All constructive comments will be appreciated. Doug N3DAB/WPRX486/WPJL709
Re: [Repeater-Builder] Guideline for scanning manuals?
George Henry wrote: What are the guidelines for scanning manuals for the RB site? There really aren't any except for common sense. Manuals that are of quality are going to be big in size, especially when the manuals have lots of pages. Newer manuals that are produced digitally are smaller in size because of the nature of the beast. The scanning process is something that takes time to perfect and then you still have that trade-off of quality verses size. That being said, we have lots of server space and size is not a concern from a hosting standpoint. This doesn't mean we should scan all manuals for availability on this (or any other) site at the highest quality / largest file size. Again, common sense tells us to have a good compromise. The exception would be a schematic or something else other than text that comes out not legible that is important to the overall value of the manual.

RE: [Repeater-Builder] DB antenna question
1. Mounting the dipoles and harness from a UHF DB420 on the same mast as a VHF DB224, or vice versa. (UHF and VHF antennas on the same mast) There will be a lot of interaction between the two. I wouldn't do this. You'd also likely need extra filtering on the ground between the VHF and UHF repeaters since the coupling between antennas will be very high. 2. Mounting the dipoles and harness from a DB420 on the same mast of an existing DB420.(2-DB420 UHF antennas on the same mast) Really bad idea. At that point, you may as well just use one antenna and a combiner/multicoupler at the bottom - you'd likely need almost the same amount of filtering with the two antennas separated on the same mast because there will be so much coupling. 3. Taking an existing DB420 antenna and feeding the upper and lower halves with separate feedlines to make 2-6 Db antennas on the same mast. The lower harness section would be replaced with with the upper harness section from a junk antenna. Better idea. This used to be order-able as a DB420D, which was really two DB408's on the same mast, one stacked above the other, with the feeders for both antennas terminating at the bottom. The isolation between antennas was something like 30 dB, so again, you'll still need adequate filtering downstairs. If any of the above ideas are practical this would allow me to recoup some additonal mounting positions or at the least reduce the clutter of antennas I have now. Can you mount two antennas on the same mount, one rightside-up, and the other inverted? If you do this, be careful if you invert-mount a DB420. The mechanical connection in the center relies somewhat on gravity to keep the two halves together; if you invert-mount, gravity is working against you. --- Jeff WN3A

It gets cut off along with the Y, the short section of VB83 and the balance of the pigtail. You should end up with a section of VB8 that you can add a new connector to.

RE: [Repeater-Builder] DB antenna question
Thanks Jeff. OK, idea 1. and 2. are basically shot down in flames. Idea 3. I can handle. Again the question, if I use the original harness how do I terminate the connector where the lower section joined the upper. Just weather proof it ?? Answer to your last comment is no All my antennas are mounted on 2 GI pipe, bracketed to the side of the house, that run from the ground to approx. 5' above the roof line (25'+/-). My site is my house located on top of a small mountain (2750'AMSL) roughly 1000' above average surrounding terrain. I also have covenents to deal with (no towers). Average coverage has been approx. 40+ miles where not blocked by higher terrain from my NW to NE. Roger on the gravity connection bit on the 2 have but a 3/8-1/2SS bolt thru the joint would solve that problem. -- Doug N3DAB/WPRX486/WPJL709 Jeff DePolo [EMAIL PROTECTED] wrote: = 1.

Re: [Repeater-Builder] Re: DB antenna question
I can't see ruining the bottom half of a good harness when I have top top half from another antenna that is been damaged that I can use. Last time I had to replace one of the connectors on a DB antenna the VB material in the cable either was still sticky or got that way from trying to solder the new connector on it and it was a real pain.
